};- Optimization and improvement
5.1. Performance optimization
Since VR surgery requires processing large amounts of data, VR surgery needs to be optimized. Some methods can be used to improve the processing speed of VR surgery, such as reducing the number of calculations and using matrix operations.
5.2. Scalability improvements
In VR surgery, different doctors may need to use different VR equipment. In order to improve the scalability of VR surgery, a replaceable VR device interface can be designed, and doctors can replace different VR devices as needed.
5.3. Security hardening
In order to improve the safety of VR surgery, some technologies can be used to prevent safety hazards in VR surgery, such as preventing rotation of the field of view in VR surgery and preventing collisions in VR surgery.
- Conclusion and Outlook
The application of virtual reality technology in the medical field has broad prospects. With the continuous development of technology, the application of virtual reality technology in the medical field will become more and more extensive.
